Analysis and evaluation of essential oil components of cinnamon barks using GC–MS and FTIR spectroscopy

In this work, the volatile compounds of cinnamon barks from three species and seven habitats were detected and identified for the first time by GC–MS and FTIR analysis. GC–MS analysis indicated that the main compound in the volatile oils of nine samples was trans-cinnamaldehyde (66.28–81.97%). Cinnamomum loureirii had the highest volatile oil yield (3.08%) and in that yield was a high percentage of trans-cinnamaldehyde (81.97%). Cinnamomum verum...
